Computed tomography (CT) frequently is used to determine torsional abnormalities. However, its use in clinical practice may be limited. We present a new method for measuring tibial torsion using conventional radiographs. We compared the method with several clinical methods and with CT measurement in 44 lower extremities of 25 subjects. The radiographic method agreed well with all of the clinical methods, and this agreement was better than agreement between CT and clinical examination. The best agreement was between thigh-foot angle and the radiographic method. The proposed radiographic measurement is a practical method for evaluation of tibial torsion in outpatient clinics without the need for specialized equipment.Level of Evidence: Level II, diagnostic study. See the Guidelines for Authors for a complete description of levels of evidence.

OBJECTIVES We evaluated the results of conservative and surgical treatment of pediatric Monteggia equivalent lesions. METHODS The study included 13 children (3 females, 10 males; mean age 8 years; range 4 to 13 years) who underwent treatment for Monteggia equivalent lesions. Seven patients (53.9%) had Bado type 1 and six patients (46.2%) had type 3 equivalent lesions. Two patients with type 3 equivalent lesions also had a lateral humeral condyle fracture. On presentation, one patient (7.7%) had radial nerve palsy. Primarily, closed reduction was attempted in all the patients except for one patient who underwent urgent debridement and irrigation for an open fracture-dislocation. Reduction was successful in eight patients (61.5%). Upon failure of closed reduction, four patients (30.8%) underwent surgery within the first 24 hours of injury. Functional assessment was made according to the Recklings criteria. The mean follow-up period was 4.1 years (range 2 to 7 years). RESULTS None of the patients had nonunion. Conservative treatment did not result in loss of reduction of the radius head or limitation in the range of motion of the elbow joint. Except for the patient with an open fracture-dislocation leading to a poor functional result, the results were good in all the patients receiving conservative or surgical treatment. One patient (7.7%) treated conservatively developed cubitus varus (5 degrees ) and posterior angulation (20 degrees ) of the ulnar fracture line. One patient treated surgically had limitation of supination (10 degrees ) without limitation of flexion or extension of the elbow joint. Accompanying radial nerve palsy in this patient disappeared in the postoperative third month. CONCLUSION Closed reduction is the first choice of treatment in pediatric Monteggia equivalent lesions. Surgical treatment becomes necessary if closed reduction fails.

Closed total talus dislocation from tibiotalar, subtalar, and talonavicular joints is a very rare injury. A 25-year-old young man, who had severe ankle distortion while walking down a flight of stairs, was brought to the emergency room complaining of a deformity and pain in his ankle joint. Roentgenographies revealed total talar body extrusion. The patient was treated urgently with open reduction in the authors’ clinic. Tibialis posterior tendon might prevent closed reduction so open reduction with retraction of the tendon may be necessary. Level of Evidence : Therapeutic Level IV

Objective The aim of this study was to assess clinical and radiological results of incomplete triple pelvic osteotomy in acetabular dysplasia. Patients and methods Twenty-six hips of 24 patients (5 males, 19 females) treated with incomplete triple pelvic osteotomy by a single surgeon from February 1995 to October 2001 were retrospectively reviewed at an average follow-up time of 12 years. The mean age at the time of surgery was 21.6 years (range: 14–41). Radiological evaluation was based on the central edge angle, acetabular angle, acetabular index, acetabular head index and lateralisation. Clinical and radiological scoring was performed using the Harris scoring system, Ömeroğlu scoring system and the Tönnis criteria for osteoarthritis. Results There was significant improvements in all of the radiological parameters with 88.5% good radiological results, 96.2% excellent clinical results, no significant progression to osteoarthritis and no need for conversion to total hip arthroplasty. The rate of major complication was 11%. Retroversion was seen in 15.4% of the hips. Conclusion Our results support the use of incomplete triple pelvic osteotomy as a safe choice in the treatment of acetabular dysplasia as it offers clinical and radiological benefits and contributes to the prevention of osteoarthritis. Level of evidence Level IV, therapeutic study.

IntroductionThis study aims to investigate the effectiveness of salicylate (Aspisol®; Bayer AG, Leverkusen, Germany) and chloroquine on preventing cartilage damage in septic arthritis.MethodsA septic arthritis model was created by inoculating the knee joint of young rabbits (n=21) with Staphylococcus aureus. Some rabbits with inflicted septic arthritis did not undergo any treatment and served as the control group (n=7). The second group (n=7) was started on salicylate on day 2 to investigate the effects of salicylate on joint cartilage. The third group (n=7) was started on chloroquine on day 2 to investigate the effects of chloroquine on joint cartilage. All three groups underwent arthrotomy, drainage and synoviectomy on day 7 of the experiment. Animals were sacrificed on day 14 and the joint cartilages were extracted. Histopathology, determination of local prostaglandin (PGE)-like activity, and evaluation of hyaluronic acid loss were performed on all samples.ResultsThe control group and the salicylate group were similar in the extent of joint damage. Salicylate did not prevent joint cartilage damage despite inhibiting PGE synthesis. Chloroquine, despite not inhibiting PGE synthesis, did prevent cartilage destruction.ConclusionIf supported by larger-scale studies, chloroquine could be added to the antibiotic regimen in the treatment of septic arthritis to prevent cartilage damage.

A meticulous capsuloplasty is needed to maintain concentric reduction in the surgical treatment of developmental dysplasia of the hip (DDH). The authors present a new capsuloplasty technique that was named as ‘reverse U-shaped capsuloplasty’. It was performed in 72 dislocated hips of 62 children with a mean age of 2.7 years. The reverse U-shaped flap, created in the redundant superolateral capsule was turned downwards, advanced medially, anteriorly and inferiorly and brought over the anteroinferior capsular incision. After a mean follow-up period of 3 years there was neither redislocation nor restriction of the hip joint motion in any hips.

A number of incision options are available to surgeons approaching the posterior aspect of the calcaneus for repair of fractures of the posterosuperior aspect of the body of the calcaneus. In this brief communication, we depict our preference for the use of a transverse posterior calcaneal incision for reduction and fixation of avulsion fractures of the calcaneus. The advantages of this particular incisional approach include adequate exposure to the underlying target structures, orientation of the scar in line with relaxed skin tension lines, which minimizes scar formation, and avoidance of dissection of the Achilles tendon.

OBJECTIVE Tailors bunion deformity is a lateral side bone and soft tissue prominence of the fifth metatarsal bone. The aim of our study was to assess the clinical and radiographic results of distal metatarsal osteotomies in patients with tailors bunion deformity. METHODS This study included 24 feet of 14 patients with tailors bunion who were treated with distal metatarsal osteotomy of the 5th metatarsal between 2006 and 2009. The mean follow-up time was 24.45 (range: 12 to 47) months. Patients were evaluated clinically and radiographically, using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system with weight-bearing anteroposterior and lateral foot radiographs. RESULTS Average AOFAS scores of the patients were 64.83 preoperatively and 91.62 at the final follow-up. Three patients had complications; avascular necrosis, delayed union, and superficial wound infection. CONCLUSION Distal metatarsal osteotomy is a safe and easy treatment option for the painful tailors bunion deformity and provides patient satisfaction rate of up to 96%.

This article presents a case of an 82-year-old woman with Alzheimers disease who was treated with a modular unipolar hemiarthroplasty for a right femoral neck fracture, which she voluntarily dislocated 3 times in the first postoperative week. The hip was stable in all directions, even in 60 degrees internal rotation, 0 degrees abduction, and 90 degrees flexion. The patient was mobilized 1 day postoperatively with full weight bearing. She dislocated her hip on postoperative day 3 while lying on her bed. After the dislocation, reduction under sedation was done again followed by a botulinum toxin injection of 50 IU to her adductor muscle group (including adductor longus, brevis, and magnus). The patient was mobilized after the injection and she had no difficulty walking. During the 6 months after the injection, no dislocation occurred again. Botulinum toxin decreases muscle activity by blocking the release of acetylcholine at the neuromuscular junction, thereby rendering the muscle unable to contract for up to 3 to 4 months. This method of botulinum injection can be applied to noncompliant patients with mental problems as an alternative conservative and surgical approaches.
